OCLC Services Unavailable Sat Aug 5th

Hi all, I just got this listserv message that all OCLC services will be unavailable Saturday Aug 5th. The message didn't say for how long. Reminder-OCLC services include the catalog, the link resolver (Journal A to Z list and "check for full text" links in databases), and WMS (the back end of the catalog used for item checkouts, renewals, collection development reports, etc.)

"As part of ongoing work to maintain and advance our systems, we will be performing a disaster recovery exercise on 5-6 August that will require system downtime. This work will be done in our U.S. data center and will impact all OCLC services. It will not impact independent European-based library management systems. While we schedule maintenance on dates and times to minimize service disruption, we recognize that this work will impact users. We apologize for any disruption this may cause. System Downtime Window: United States Data Center: Saturday, 5 August 2017, 23:00 EDT–Sunday, 6 August 2017, 08:00 EDT (Eastern Daylight Time UTC -4) Thank you for your continued support. If you have any questions about this upcoming event, please contact your local customer support team."

Thanks, Lea
